This study aims to develop a neural network-based method for predicting patient-specific organ doses from chest CT scans, utilizing hybrid patient size vectors for enhanced computational efficiency, accuracy, and generality. A dataset of 705 chest CT scans was retrospectively analyzed to construct predictive models for organ dose estimation.

Patient centering effects on Size-Specific Dose Estimates (SSDE)
2017Background/Introduction: The concept of Size-Specific Dose Estimates (SSDE) for refining computed tomography (CT) dosimetry has been proposed in the Report of the American Association of Physicists in Medicine (AAPM) Task Group 204.[1] The present conventional metrics for...

Introduction and evaluation of size-specific DLP for radiation dose estimation in CT examinations
Journal of Radiological ProtectionAbstract The increased utilization of computed tomography (CT) has raised concerns about patient radiation exposure. Effective dose (ED), which requires precise estimation, is crucial for assessing and managing these risks. Traditional ED estimation methods, which are based on the dose-length product (DLP), often lack accuracy due to ...

Size specific dose estimation in pediatric CT: preliminary study and conversion factors
Radiation Protection DosimetryAbstract The objective of this paper is to compare the differences between volumetric CT dose index (CTDIVOL) and size-specific dose estimate (SSDEWED) based on water equivalent diameter (WED) in radiation dose measurement, and explore a new method for fast calculation of SSDEWED.

Computed tomography angiography (CTA) is a widely used diagnostic tool, but concerns about radiation exposure necessitate accurate dose estimation. This study investigates the correlation between Effective Dose (ED) and Size-Specific Dose Estimate (SSDE) estimated from the patient's body mass index (BMI) in CTA to evaluate the utility of SSDE-BMI as a ...
